This was Jack’s third visit to the city in the past two months, said an officer of the narcotics cell. His Indian visa expires in the middle of June.

“The charas was neatly packed in a plastic packet that Jack was carrying in a shopping bag. He was on his way to deliver the charas to an associate in the red-light area but was caught before he could hand over the packet,” said the officer. Jack’s driving licence and a knife were seized.

“He had entered the state through Nepal. During his earlier visits too, he had brought charas with him. He also had planned to visit the city twice more before his visa expired,” said the officer.

The police are trying to find out how Jack was sourcing the drug and also the names of his associates in the city.

“Jack could be a part of a big drug cartel. We are trying to find out who his other associates are in the city,” said another officer.
